A childhood belief about excursions

Whenever we drove past the Jack Astor's, I always read the writing under the logo as "Boy & Girl." I thought that maybe Jack was the boy and Astor was the girl and they founded the restaurant together. I never really questioned why Astor was a strange name. A couple of years later, after finding out I was near-sighted and had gotten glasses, we came across the sign again. I could now see that the sign read:

"Bar & Grill"

D'oh!
